Impact Evalua,on
• Impact was evaluated using an instrumented sphere (TechMark Inc.) on the tradi;onal equipment and on the new one.
Figure 3. Instrumented sphere used for impact evalua;on.
Impact Trials • Impact trials were performed on the sor;ng equipments: Conven;onal and the new
one at two different rota;ons: 120 and 180 rpm. Preliminary tests using an instrumented sphere showed impact magnitude lower in the new system.
